I bought this in order to have a place to keep lyrics and chords for songs. Mainly I've been using it when i rehearse with my band and in this use it has been great!
Thanks to the well built arm it's easy to get the holder positioned exactly where you want it. Like all other K&M products the sheet holder is built really well and although it has many screws, once tightened the holder is really stable.
Since this sheet holder is a bit on the small side, it barely holds two A4 size papers next to each other. Sometimes I find myself in the need of a bigger one, but since this is fastened to a micstand, I think a bigger would be a bit over sized.
To summarize, I think this is a good sheet holder but it might be a good idea to have a separate stand for all your papers.
